kendo window vertical align middle

아래처럼 해보니 되었다

.k-window {
    position: absolute !important;
    top: 50% !important;
    left: 50% !important;
    transform: translate(-50%, -50%) !important; /* 중앙 정렬 */
}

$("#kendoWindow").kendoWindow({
    width: '800px',
    size:"auto",
    resizable: false,
    title: "KendoWindow",
    visible: false,
    modal: true
});
